    TP-Link TL-WN822N is not ready

    Hi,
    I've bought external network card TP-Link TL-WN822N. I've installed drivers as is written here: http://www.ajaykumarsingh.com/linux/...#comment-34551 and it has been working pretty good, but after updating kernel from 3.8.0-33 to 3.8.0-34 the device "is not ready" and it doesn't work. So the question is how can I resolve this problem? Maybe the best way will be when I'll uninstall all drivers associated with this device, but how to do it?

    Regards.

    Re: TP-Link TL-WN822N is not ready

    The process you linked compiles a driver against the currently running kernel only; in your case, 3.8.0-33. Now that you are running 3.8.0-34, simply re-compile:
    cd to the folder where you unzipped the driver and run following commands. If you are not root then use sudo before these commands where required.

    chmod 755 ./install.sh
    ./install.sh
    You should be all set.

    Yep, now the device is displayed, but still it's trying to connect to a network and asking about password although I've entered it correctly. Moreover, LED isn't lighting although the device is plugged in.

    Please temporarily try the old driver:
    Code:
    sudo modprobe -r 8192cu
    sudo modprobe rtl8192cu
    Is the behavior improved?

    Re: TP-Link TL-WN822N is not ready

    Code:
    sudo modprobe -r 8192cu
    Deleted the device from the list.

    Code:
    sudo modprobe rtl8192cu
    I've received a message:
    FATAL: Module rtl8192cu not found.
    To sum up, nothing changed. So maybe totally uninstalling all drivers and installing them again will help?

    Before we proceed to more drastic methods, let's check the log:
    Code:
    sudo modprobe 8192cu
    dmesg | grep -e 8192 -e rtl

    Interesting:
    [ 8.929844] rtl8192cu driver version=v4.0.2_9000.20130911
    I thought that we were using 8192cu and not rtl8192cu and that, furthermore, the system couldn't find rtl8192cu:
    FATAL: Module rtl8192cu not found.
    Let's double-check:
    Code:
    lsmod

    I can't see neither rtl8192cu nor 8192cu as used. Now when I'm checking the device is disconnected on the list.

    ...and here?
    ath9k_htc 92962 0
    How many conflicting drivers can we load at one time?? Do you have an internal device that we ought to either troubleshoot and get going properly or did you make a few additions to /etc/modules or ... what??

    May we have a peek?
